Collect a number of different binaries compiled with different options,
|
|
all based on 1.2.pre1. Develop some process, such as booting linux,
|
|
compressing some big file, and then rebooting that takes a while.
|
|
Time how long each binary takes to execute that task.
|
|
|
|
Problems with reboot!
|
|
1.2.pre1 didn't actually do reboot right!!!!!!!!!
|
|
what a pain, all these binaries are compiled by hand.
|
|
Maybe I can make a script to compile them all again.
